Title:
DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/107025
Kind Code:
A1
Abstract:
Disclosed is a detection device (10, 20, 30), comprising a base plate (100, 700), a cover body (200, 800), a micro-sensing chip (300, 900) and a micro-channel structure (400), wherein at least one of the base plate (100, 700) and the cover body (200, 800) contains a porous material. The base plate (100, 700) has a first surface (101), a groove (102, 702) is provided on the first surface (101), and the groove (102, 702) comprises a bottom part (103) and a slope (104), wherein the bottom part (103) is embedded into the base plate (100, 700), the slope (104) connects the first surface (101) with the bottom part (103) and is configured to one end, close to an injection port (402, 810), of the groove (102, 702). The cover body (200, 800) has a second surface (201) facing the first surface (101). The micro-sensing chip (300, 900) is embedded into the base plate (100, 700). The micro-channel structure (400) is embedded between the second surface (201) and the first surface (101) to form a micro-channel (401, 802). An object to be detected (600) enters from the injection port (402, 810) into the groove (102, 702) via the micro-channel (401, 802), and is separated into a lower layer liquid (601) and an upper layer liquid (602), wherein the lower layer liquid (601) is retained on the bottom part (103), and the upper layer liquid (602) flows from the groove (102, 702) to the micro-sensing chip (300, 900), and no additional power needs to be applied to the detection device (10, 20, 30) during the detection process of the object to be detected (600).
